Summary of the Project

In 2019, Unique Group’s Diving & Life Support teams in Cape Town and Houston successfully collaborated to complete the build of an HYDRACraft 1400 Diving Daughtercraft system. This was the first-ever project undertaken by the team in Houston for a Diving Daughtercraft system for the South American market.

Client Requirement

The client, Oceanpact, requested Unique Group to manufacture an Air Diving Daughtercraft to fit within their project budget and schedule constraint for deployment to support offshore diving operations in Brazil.


  • A short timeframe to deliver the completed product was one of the major challenges faced during the project as this was one of our first major diving product sales directly to the Brazilian market
  • An attractive discount was also offered to the client to successfully win this order
  • The overall weight of the vessel including the dive system and additional payload had to be within the operating limits of the Davit
  • Remote assistance and during integration with the mother vessel and Davit launch system

Unique Solution delivered

The project consisted of two main components: the vessel and the 10T launching Davit. To achieve the tight timeline, Unique Group proposed to ship the Davit directly from the fabrication shop in Poland to the client location in Brazil. Unique Group collaborated with Veecraft Marine for the build of the Daughtercraft and the fit-out of the Diving equipment in Cape Town. Commercial diving expertise, product familiarity and an in-house design enabled Unique Group to assemble the complete HydraCraft system, inclusive of the Davit and vessel, at the clients’ site. Sea trials and function testing of the Daughtercraft took place in Cape Town and exceeded client requirements.
